Abstract
To resume data writing onto a disk, a recording start position detection means detects a recording start position, and a synchronous setting means synchronizes recording data with recorded data on a disk so that recording data successive to the recorded data on the disk can be additionally written onto the disk without a break. Data writing onto a disk is suspended until an amount of data equivalent to data writing capacity has been stored in the buffer memory. Data writing is resumed upon detection of the fact that an amount of data equivalent to data writing capacity has been stored in the buffer memory. With the above, power consumption can be reduced during a period when recording capability of a disk recording device exceeds the data transfer speed.

When the external mechanical that is connected splicing ear 11 send to require the data of record, these data received by interface 10, among the write buffer RAM13.Then, the data among the write buffer RAM13 are modulated into the record data that should write down form in the dish by scrambler 12.
During the writing position of the position arrival dish of the laser beam flying by laser head 1, is unit output record data successively from scrambler 12 with the EFM frame, and expression updates stored among the addressed memory 15a that has in the system, control circuit 15 successively to the address date of the recorded data addresses that should export.
When buffering underrun state takes place when, perhaps because of reasons such as impact can not to the dish in write down state the time, can interrupt the judgement of record in dish by recording control apparatus 18, interruption is from scrambler 12 output record data, stop simultaneously writing light beam, the record in dish is interrupted from laser head 1 ejaculation.When the record data from scrambler 12 outputs interrupt, in before record interrupts, being stored in addressed memory 15a in the system, control circuit 15 from the pairing address date of last frame address of the record data of scrambler 12 outputs, institute's address stored data become auxiliary code Q channel data (assisting the Q data) temporal information and represented which number address information of the EFM frame in its time information.And, synchronization settings device 20 is according to institute's address stored data among this addressed memory 15a, what time somewhat the recorded data addresses of the last frame that writes down in dish is which frame according to the temporal information in the auxiliary Q data, to being which EFM frame in this temporal information manages.
When receiving the next data that require record by interface 10, memory control device 16 carried out access, the scanning of beginning laser head 1 to the record data of record in the dish ATIP by 7 demodulation of ATIP demodulator circuit before interrupting.
After the scanning beginning, read by being recorded in dish and go up the position signal that forms, obtain the EFM data from RF amplifier 2.
Then, system clock converts the playback clock with the EFM data sync to, and the modulation treatment of the demodulation process of demoder 4 and scrambler 12 becomes the state that carries out with the playback clock synchronization.
When requiring next data of record by interface 10 inputs, scrambler 12 restarts the modulation treatment action, restarts to form record data.
On the other hand, when dish is scanned, when the EFM data are input to demoder 4, synchronizing signal by demoder 4 extraction auxiliary codes, carry out demodulation by 5 pairs of auxiliary Q data of auxiliary code demodulator circuit simultaneously, by synchronization settings device 20, the record data that utilize above-mentioned synchronizing signal and auxiliary Q data that the record data that are recorded in the dish are exported scrambler 12 carry out synchronously.
Obtain this before synchronously during, scrambler 12 is with reference to address stored data among the addressed memory 15a, becomes the holding state of record data output of the next frame of the last frame that will be write down in the dish before record interrupts by recording control apparatus 18.
Herein, in scrambler 12, have for carrying out the internal RAM of modulation treatment, this internal RAM is guaranteed data necessary in the CIRC processing for the input data of new input being guaranteed staggered (the ィ Application one リ one Block) length (maximum 108 frames in the EFM frame) of necessary CIRC in the time of will interrupting at the record of record data.
When scrambler 12 was in holding state, with reference to address stored data among the addressed memory 15a, the beginning position of the not posting field after the posting field that has write down by record data in 19 pairs of dishes of record start position pick-up unit was detected.
This not the detection of posting field beginning position be to be undertaken by the temporal information of auxiliary Q data and which the EFM frame in this temporal information, pass through auxiliary Q data retrieval before the unit of auxiliary code frame (set of EFM frame 98 unit quantities), and EFM frame unit is to be benchmark with the synchronizing signal, by the counting channel position end of the last frame of the record data of record in the dish is judged.
When detecting the beginning position of last posting field, when system clock progressively is transformed into reference clock from the playback clock, from scrambler 12 output record data, restart in dish, to carry out record by recording control apparatus 18.
In the moment of restarting record in dish, the record data that have been recorded in record data in the dish and scrambler 12 outputs by synchronization settings device 20 are obtained synchronously, and the record data of the next frame that write down dish before the record interruption from scrambler 12 outputs.
Therefore, before record interrupts, from dish the new record data of the mutually continual link position opening entry of last record data of record, the new recorded data of record and the consecutive frame of frame of last record data simultaneously.
As a result, realized additional record by (disk-at-once) mode of once depositing.
Below the data processing speed that writes record data on the dish in disc recording apparatus is described than the situation that the data rate from transmitting terminal has high-speed ability.
Disc recording apparatus shown in Figure 1 has the high-speed record ability of 8 times of speed of the standard speed of CD specification specifies, suppose by splicing ear 11, by the data that interface 10 received are continuous data such as voice data and video data, and its transmission speed is a specified standard speed in the CD specification.
Like this, when the registering capacity of disc recording apparatus is compared with the transmission speed that receives data when having high speed, recording control apparatus 18 is according to the data capacity of storing among the impact damper RAM13, the record halted state of time-out and the recording status that writes down are write down in setting in dish in dish, compare with the transmission speed that receives data, during the surplus when registering capacity of disc recording apparatus is superfluous, the record of stop disc.
Below with reference to Fig. 2 this action is described.
Among the data write buffer RAM13 that receives by interface 10 by splicing ear 11 (S1).
The data capacity of being stored in impact damper RAM13 judges that as writing data area in advance the ormal weight that allows writes the full capacity (S2) of permission capacity.When not reaching full capacity, be set at the record halted state that in dish, stops to write down by recording control apparatus 18,17 couples of impact damper RAM13 of impact damper control device stop data and read (S3), return S1 then, only carry out writing of data.
Herein, the external mechanical that connects on the splicing ear 11 is a personal computer, when transmitting terminal can be controlled the data transmission that requires to write down by disc recording apparatus according to the situation that writes of dish, by stopping the data of this transmission, just can prevent overflowing of impact damper RAM13, the full capacity that writes allowance among the therefore above-mentioned impact damper RAM13 just means the full capacity of the memory capacity of impact damper RAM13.
On the other hand, the external mechanical that connects on splicing ear 11 is a CD-audio player, no matter the write state by disc recording apparatus dish how, when transmitting terminal sends the data that require record always, if the data capacity of being stored among the impact damper RAM13 has arrived full capacity and has also write data, then before the impact damper RAM13 sense data among restarting to the dish of detection of record start position etc., to write down preparation, must write data to impact damper RAM13, because impact damper RAM13 will overflow, therefore, the full capacity that at this moment writes allowance in impact damper RAM13 just means estimate the resulting capacity of data capacity that writes among the full capacity of the memory capacity of impact damper RAM13 deducts to dish the preparation of record again.
In addition, when being set at the record halted state by recording control apparatus 18, the supply of each circuitry cuts working power of being surrounded by 21 pairs of Fig. 1 dotted lines of pause in action control device, the data-modulated that stops scrambler 12 handle action, the write activity in dish, the action of the data read from dish, and the playback of the reading of data of dish handle action.
Therefore, when the setting recording halted state, the power consumption in each circuit that Fig. 1 dotted line is surrounded will be cut down.
On S2, when the data capacity of being stored among the impact damper RAM13 reaches the full capacity that writes allowance, remove the record halted state by recording control apparatus 18, be set at recording status.
When being set at recording status, again supply with working power by each circuit that dotted line surrounded among 21 couples of Fig. 1 of pause in action control device, the data-modulated of restarting scrambler 12 handles action, the write activity in dish, from dish reading of data action, and the playback of the reading of data of dish handle action.
For this reason, the data of storing among the impact damper RAM13 are carried out modulation treatment by scrambler 12, be transformed to record data after, be recorded in (S4) in the dish by laser head 1.
Herein, being recorded in before record interrupts in dish, the position that uninterruptedly connects mutually from the last record data of record begins to carry out, the data that in dish, write down become with interrupt before the consecutive frame data of frame of last record data.This action is identical with above-mentioned situation.
But when the record halted state, the rotation of dish does not stop.
At this moment, motor servo circuit 9 console panel motors 8, halted state rotating speed before makes it to hold the record.
Therefore, can shorten from changing recording status arrives the suitable rotational speed that writes down to dish time.
In addition, a servo circuit 3 storages forward the DC voltage level of the focus control signal before the pause in action state to, when the pause in action state is removed, its DC voltage level are produced as focus control output.
Therefore, when conversion during recording status, the focus of the light beam that is undertaken by laser head 1 forwards to consistent with the mean state of focus control before the pause in action state, so can forward the focus servo state immediately to.
Thereby, can shorten from writing down halted state and remove the time that the dish of the record start position that detects placing reads, can shorten the time of coiling record again that reaches.
Owing to can shorten the time of restarting to coil record that reaches, thus can prolong the record halted state during.
Promptly, the condition of removing the record halted state is that the data capacity stored in impact damper RAM13 is when reaching the full capacity that writes allowance, if so from removing the record halted state to the time shortening that restarts to coil record, just can make the sequential time delay of removing the record halted state, this amount is not in producing the scope of overflowing, can in impact damper RAM13, store a lot of data, can effectively utilize impact damper RAM13.
And, in impact damper RAM13, before data do not have, in dish, write data (S5, S1), and when data do not have, forward S3 to, stop in dish, writing data.
In the above-described embodiment, by pause in action control device 21, cut off the working power that each circuit of the dotted line among Fig. 1 is supplied with, but also can not cut off working power but the cut-out work clock, the action of above-mentioned each circuit is stopped, thereby reduce the power consumption of each circuit.
In the above-described embodiments, though, can reduce power consumption corresponding to various recording modes of other grouping writing modes that comprise once deposit, tracking or bout mode to not explanation of recording mode.
